A selective deslagging operation is conducted in a partial oxidation reactor wherein a first predetermined portion of the reactor is selectively deslagged by derivatization while limiting derivatizing slag conditions in a second predetermined portion of the reactor. Selective deslagging can be accomplished by controlled oxidation conditions in the reactor that vary from one predetermined portion of the reactor to another. Thus, the slag present in one predetermined portion is derivatized and fluidized for removal from the reactor at a faster rate than the slag present in another portion of the reactor, which is not derivatized or is subjected to more limited derivatizing slag conditions. Derivatized slag can be differentiated from non-derivatized slag that does not flow or more limited derivatized slag that has a lower mass flow rate then the derivatized slag at conditions of controlled oxidation. The derivatized slag can then be selectively removed because it has attained a lower fluidizing temperature.
